Judaism intersects with environmentalism on many levels. This article addresses how the natural world plays a central role in Jewish law, literature, and liturgical and other practices. Moreover, within the diverse arena of Jewish thought, beliefs vary widely about the human relation to the environment. In addition, the article looks at the history of Jewish environmental thought and activism.

Generally speaking, the Bible and rabbinic tradition have put Judaism primarily on an anthropocentric trajectory, but creation-centered or eco-centric interpretations of Judaism can also be found throughout Jewish history, many theologians regard the land as a primary partner of Jewish covenant, and Judaism and especially the practices described in the Torah may be regarded as the expression of a fully indigenous and land- or earth-centered tradition. In Genesis, too, God instructs humanity to hold dominion over nature, but this may be interpreted in terms of stewardship as well. Eco-centric discussions of Judaism can be found in the work of such modern scholars and rabbis as Arthur Green, Arthur Waskow, Eilon Schwartz, Lynn Gottlieb, Mike Comins, Ellen Bernstein, and David Mevorach Seidenberg.

The Jewish environmental movement[1] has developed on parallel tracks in North America and in Israel. In North America it was in many ways motivated by the revival of back-to-the-land values in the sixties and seventies. However, whereas for the majority of the counter-culture movement these values were an expression of 1960’s radicalism, for Jews there was the additional and powerful influence of Zionist idealism, which since its inception also emphasized returning to the land. Especially after the 1967 Arab-Israeli war, which generated a huge outpouring of sympathy and identification with Israel among unaffiliated Jews, the motif of return to the land became a bridge that connected progressive Jewish activists with the Jewish community from which they were often estranged. In Israel various initiatives, movements, and thinkers, like the JNF, the kibbutz movement, and Ahad Ha'am, may be seen as forerunners of Jewish environmentalism, though those these trends were not always in line with an explicitly Jewish environmentalist understanding.

The pioneers of environmentalism in the North American Jewish community were often deeply committed to vegetarianism. (This trend can still be found in newer organizations like the Shamayim Va'aretz Institute and Farm Forward. ) Notable among the early innovators is Richard Schwartz, who published Judaism and Vegetarianism in 1982, followed by Judaism and Global Survival in 1984.

As with most things Jewish, a large part of Jewish environmental work has consisted of investing Jewish practice with ecological meaning through sermons, teachings, and books. Two early writers were Eric Freudenstein[2] and Rabbi Everett Gendler,[3] who also influenced a great many activists and teachers during this period through his teaching and his farming. Rabbi Arthur Waskow has been one of the leaders in this area of exploration, starting with his 1982 work The Seasons of Our Joy: A Modern Guide to the Jewish Holidays,[4] which follows the liturgical calendar through the changes in the earth. (Waskow’s work was part of a trend now called Jewish Renewal, which involved uniting values associated with 1960s or New Age spiritual countercultures with Jewish practice.) In the same year, David Ehrenfeld and Rabbi Gerry Serotta at Rutgers University organized the first-ever Jewish Environmental Conference. In 1983, Waskow founded the Shalom Center, which over time turned its energy from nuclear weapons to the environment. The Shalom Center is now one of the primary organizations in North America and the world that promulgates an activist ecological understanding of Judaism.

In 1988, Shomrei Adamah (“Guardians of the Earth”) burst on the scene as the first national Jewish organization devoted to environmental issues. Founded by Ellen Bernstein in Philadelphia, Shomrei Adamah produced guides to Judaism and the environment such as Let the Earth Teach You Torah (1992), which was one of the works that initiated the field of Jewish environmental education. Shomrei Adamah captured the imaginations of environmentally concerned Jews around North America and quickly supplanted groups such as L’OLAM in New York City on the national level. However, even as regional groups like Shomrei Adamah of Greater Washington DC (founded in 1990) sprung up to do grassroots organizing, the national organization pulled away from involvement with regional groups. Later, other regional groups like the Northwest Jewish Environmental Project in Seattle (NWJEP or NJEP), founded in 1997, took a decidedly different approach. While Jewish identification with the earth and Jewish environmental activism had gone hand-in-hand up until then, these new groups focused on making nature a source of Jewish identity and explicitly de-emphasized political activism. The roots of this approach can be traced back to Jewish hiking groups and to the national network of such groups, Mosaic Outdoor Clubs of America (founded in 1988).

In 1993, The Coalition on the Environment and Jewish Life (COEJL) was formed to bring the Jewish environmental movement into the mainstream. COEJL filled the vacuum left by Shomrei Adamah, working with other religion-based groups under the umbrella of the National Religious Partnership for the Environment (NRPE) to achieve these goals. Unlike earlier groups, which were created by activists or organizational entrepreneurs, COEJL was founded by three institutions: The Jewish Theological Seminary (of the Conservative movement), the Religious Action Center (the lobbying arm of the Reform movement), and the Jewish Council for Public Affairs (previously the National Jewish Relations Advisory Council), the national umbrella for the Jewish Community Relations Councils that can be found in most metropolitan areas. Jewish environmentalists are drawn from all branches of religious life, ranging from Rabbi Arthur Waskow's organization The Shalom Center to the Orthodox educational group Canfei Nesharim.

The newer generation of Jewish environmental organizations, including especially the farming and food movement, can be traced to the Teva Learning Center, now called the Teva Learning Alliance, which was founded in 1994 by Amy Meltzer and Adam Berman at Camp Isabella Freedman in Connecticut to offer outdoor education experiences to Jewish day schools. Teva's initial curriculum drew on resources developed by Camp Tawonga, located in the California redwoods. Teva has long been a flagship of Jewish environmentalism, which now embraces numerous organizations and activities. The Adamah Farming Fellowship was also founded in 2003 at IF (now called the Isabella Freedman Retreat Center) by Shamu Sadeh, an alumnus educator of the Teva program. In the past few years, Jewish environmental consciousness has poured itself into the farming movement, sparked by Adamah, and the food movement, focalized by Hazon. For a more comprehensive view of North American Jewish environmental organizations, see the Jewcology "map of initiatives".

Hazon itself was founded by Nigel Savage in 2000 with an inaugural bike ride across North America to raise money for Jewish environmental causes in North America and Israel. Hazon has expanded greatly since then, and has nurtured through conferences and incubation grants the Jewish food movement and the campaign to bring awareness of the Sabbatical year to the Jewish community throughout the world. Other efforts include neohasid.org, founded by Rabbi David Seidenberg in 2005, Wilderness Torah, founded by Zelig Golden in 2009, and Eden Village Camp, which was first envisioned by Yoni and Vivian Stadlin in 2006 and which opened in 2010. Eden Village has grown rapidly in size and influence. Most importantly for the advance of Jewish ecological thought, the Kayam Farm at Pearlstone, founded 2006, organized an annual conference on Jewish agricultural law. In 2013, Hazon, already the largest Jewish environmental organization in North America, merged with Isabella Freedman. Along with the proliferation of farming programs in North America, and a network of Jewish-community-based CSA’s organized by Hazon, there has also been a movement to bring shechitah, kosher slaughter, back to the small farm, using humanely- and sustainably-raised animals. Grow and Behold Foods (founded 2010) is the largest commercial purveyor of such meat. There is also wide interest in a kosher certification that would guarantee food is produced in an ethical manner. In 2014, Hazon took over Isabella Freedman Retreat Center, creating the most powerful Jewish organization devoted to environmental issues.

In Israel, many governmental and non-governmental organizations, both secular and religiously oriented, exist to protect nature and to advocate for environmental issues and for environmental awareness.[citation needed] The Heschel Center for Environmental Learning and Leadership, and the Reform movement’s Kibbutz Lotan, both founded in 1983, have had a long and lasting impact. In 2001, the Green Zionist Alliance, now called Aytzim, was founded as the first environmental organization to ever participate the World Zionist Organization and its constituent agencies. The Green Zionist Alliance works from North America to educate and mobilize Jews around the world for Israel’s environment and to support Israel's environmental movement.[5] From 2003 through 2008, Rabbi Carmi Wisemon together with the Ramat Shlomo Community Council, the Israeli Ministry of the Environment and the Municipality of Jerusalem produced four journals called the Environment in Jewish Thought and Law, on the intersection between Halacha (Jewish law) and environmentalism written by Orthodox rabbinic scholars. Sviva Israel. Notable recent developments include Teva Ivri, founded in 2009 by Einat Kramer, which led the Shmita Yisraelit movement and project, The Interfaith Center for Sustainable Development, founded in Jerusalem in 2010 by Rabbi Yonatan Neril, and Shorashim/Roots, a peace group founded in 2014 in the West Bank by both settlers and Palestinians that focuses on land issues.

In contemporary Jewish liturgy, ecological concerns have been especially promoted by adapting the kabbalisticritual of conducting a seder for the New Year of the trees, Tu Bishvat.[6] Biblical and rabbinic texts have also been enlisted for prayers about the environment in all the liberal movements, especially in Reform Judaism and Jewish Renewal movements.

Perhaps most emblematic of the nexus of Judaism and the environment is the growth of the primary Jewish environmental event to which most Jews have been exposed, the aforementioned Tu biSh’vat seder, often labeled “Jewish Earth Day” and sometimes called tongue-in-cheek "Tree B'Earthday". Falling in the early spring two full moons before Passover, Tu biSh’vat (“the 15th of the month of Sh’vat”) generally coincides with the first sap rising in the fruit trees in the land of Israel. Because in rabbinic Judaism this day was labeled the “New Year for the Tree,” 17th century mystics created a ritual meal or seder of fruit and nuts for the day that celebrated the “Tree of Life” that sustains the universe. The Jewish National Fund (JNF) applied these motifs to in the 1950s to championing Tu biSh’vat as a day for planting trees in the land of Israel.

The history of the seder also sheds light on the development of the Jewish environmental movement. One of the early moments of awakening to environmental issues in the Jewish community came when rabbis and Jewish activists drew on the symbolism of the Jewish National Fund campaigns to create the “Trees for Vietnam” reforestation campaign in 1971 in response to the use of Agent Orange by the US. In 1976, Jonathan Wolf in New York City created and led one of the first modern environmental seders, incorporating liturgy from the Kabbalists with information from Israeli environmental groups like Neot Kedumim (“Ancient Fields,” a conservancy group devoted to Biblical species), and Society for the Protection of Nature in Israel (SPNI).

By the late-1970s, Jewish groups around the country were innovating rituals for Tu biSh’vat that connected Biblical and rabbinic teachings with material from the Kibbutz movement or JNF and with current environmental concerns. In the 1980s dozens of homemade Tu biSh’vat liturgical books or haggadot modeled after the Passover seder were being used around the country to celebrate trees and to talk about local and national environmental issues, the earth and ecology. A wealth of material on Tu biSh'vat can be found today on neohasid.org, COEJL, and jewcology.org.

Other liturgy includes resources for Rosh Hashanah and Yom Kippur, Sukkot, and Passover, a Hebrew translation of Pope Francis's prayer from Laudato Si, adaptations of the Hoshana Rabbah liturgy, and much more.
